Example Embodiment

[0026] The present invention will be further described below in conjunction with the accompanying drawings of the specification:

[0027] Such as figure 1 As shown, the equipment specially designed to implement a push-pull flexible shaft outer tube buckle riveting method includes hydraulic system, pneumatic system, buckle riveting mold, frame, etc. The hydraulic cylinder 5 is axially arranged and fixed on the frame 13. The buckle riveting mold includes an outer mold 4 with an inner taper hole and an elastic compression die set 6 whose outer taper surface matches the inner taper hole of the outer die. The elastic compression die set 6 is fixed on the frame or the cylinder block of the cylinder. The upper stop 11 is in contact with each other, the taper of the inner cone of the outer mold is 25°-65°, the elastic compression die set 6 is composed of 6-16 die sleeves and the compression die plate 7, and a spring 14 is installed between each die , The crimping surface of the die piece...

Abstract

The invention discloses a method and equipment thereof for buckling-riveting an outer sleeve of a push-pull flexible shaft, which are used for automobiles or engineering machinery and the like. Through the method and the equipment, an inner hole of an inner lining tube can be effectively prevented from deformation, the tensile force bearing capacity of a pipe joint is improved, and the service life of the push-pull flexible shaft is prolonged. The method comprises the following steps of: inserting the inner lining tube of a pressure hose inserted into a sleeve joint and placing the sleeve joint onto a buckling-riveting mold; starting a hydraulic system, making an external mold axially move to force an elastic mold pressing element set, so that mold pressing elements are radically retracted to rivet and press the sleeve joint; and changing a direction, making a piston rod of an oil cylinder drive the external mold to reversely move, expanding the elastic mold pressing element set and pulling a core rod out. The buckling-riveting equipment comprises the hydraulic system, the buckling-riveting mold, a stander and the like, wherein the buckling-riveting mold is provided with the external mold with an inner taper hole and the elastic mold pressing sheet set formed into an outer conical surface; springs are arranged between every two mold sleeves; the elastic mold pressing element set is in contact with a stopper; the piston rod of the oil cylinder is connected with the external mold; and a core pulling device comprising a cylinder and the core rod is arranged axially.

Description

technical field [0001] The invention relates to a riveting method and equipment for push-pull type flexible shaft outer tube buckle and riveting used in automobiles or engineering machinery. Background technique [0002] At present, the riveting of pressure-resistant hoses and metal pipe joints for automobiles and construction machinery is done by punching and riveting technology, which is divided into upper and lower molds for riveting. The shape of the upper and lower molds is hexagonal or octagonal, and the lower mold is fixed on the static lower mold base. Upper, the upper mold is fixed on the movable upper mold base. When the pressure-resistant hose and the metal pipe joint are riveted, the upper mold base moves downward to impact the sleeve joint, causing the sleeve joint to produce plastic deformation and squeeze the pressure-resistant hose , so that the pressure-resistant hose and the metal pipe joint are tightly connected and can withstand high tension. When punchi...
